WATER-FILTER.

Application filed July 14, 1914.

To all whom it may concern Be it known that I, HENRY L. KUnNzLI, a v citizen of the United States, and a resident of Nevada, in the county of Wyandot and State of Ohio, have invented a new and useful Improvement in Water-Filters, of which the following is a specification.

My invention is an improvement in water filters, and has for its object to provide a device of the character specified, for interposition in the pipes leading to cisterns or other receptacles for rain water, and wherein mechanism is provided, arranged within the length of the pipe and between the receiving and the delivery ends for filtering the water during its passage and for removing sediment of all character from the water, and wherein the said removing means is so; arranged-that the action of the water coming on to the said means will clean the sediment from the cleaning means and deliver it outside of the pipe.

' A further object is to provide a removable screen that may be taken out and replaced or renewed, and to provide mechanism in connection with the screen and the filter for preventing loss of water through the opening for the discharge of'theimpurities by splashing or by capillary attraction.

In the drawings Figure 1 is a front view of an improved filter, Fig. 2 is a sec. tion on the line 22 of Fig. 3. Fig. 3 is an enlarged section at right angles to Fig. 2, Fig. 4 is a section on the line 4.-l of Fig. 3, Fig. 5 is a perspective view of a portion of the screen supporting frame, and Fig.6 is

an enlarged section "of the lower end of the screen. a

The present embodiment of the invention comprises a casing 1 of substantially rectangular cross-section, having a top 2 and a bottom 3. The bottom is hoppershaped, as shown, for preventing the damming up of water inthe bottom of the filter, and the outlet of the bottom is provided with a nipple or pipe section 4, for engaging the supply pipe of the cistern or other receptacle;

The top 2 is provided with a nipple or'pipe section 5, with which one of the arms of an elbow 6 is engaged. The pipe section or nipple 5 and the elbow are annularly beaded as indicated at 7, and the beads fit within each other to provide for a rotatable connection of the elbow with the casing, and to prevent disengagement of the elbow and the casing. The arms of the elbow are at an Specification of Letters Patent.

obtuse angle with respect to each other, the arrangement being such that when the arm engaged with the pipe section or nipple 5 is perpendicular the other arm will be inclined upwardly at about the angle of the down spout or conductor pipe of a building.

1n the present embodimentof the invent on the body 1 of the casing is made from a single sheet of sheet material and the joint is at the front as indicated at 8. At this polnt an opening 9 is provided, the said openlng being encircled by. a reinforcing wire frame 10. The frame 10 is substantlally rectangular, and a portion of the material of the casing is bent over or beaded around the frame as shown, to hold the frame in place and to provide a rigid wall at every side of the opening.

The screen comprises a substantially rectangular frame, consisting of side members 11, an upper end member 12, and a lower end member 13. Each of the side members near its lower end is doubled backward upon itself as indicated at 14;, and is then bent forwardly and downwardly as indicated at 15, to a connection with the end member 13. A covering 16 of perforate material, as for instance, wire mesh of suitable size, is supported by the frame. The covering 16 is on the front of the frame when in place, and the said covering extends downward in a double fold between the doubledeover porwardlv along the portion 15 to the end member 13, to which the lower end of the covering is connected.

It will be noted from an inspection of Fig. 6, that the doubled-over portions of the screen are rigidly connected at the upper end of the portions 15, the said connection being by means of solder or the like, and extending the full width of the screen. The rear face of this solid portion it will be noted is flush with the rear face of the covering of the screen, so that no impediment is offered to the flow of water down past the solid portion.

It will be noticed that each of the portions 15 of the frame isarched or curved slightly longitudinally, the concavity being upward, andthe covering 16 follows the shape of the said portion. The solid portion formed on the front of the screen along the tions 14 of the side members and thence fori upper face of the solid portion 17 and on that portion of the screen connected to the outside of the lower end member of the frame 10 to lock the screen from rearward movement at this point. The upper end of the screen fits beneath a deflecting plate, consisting of a portion 19, fitting the rear face of the casing 1, and secured thereto by means of bolts and nuts 20, and a portion 21 which extends outwardly and 'downwardly from the rear wall of the casing over the upper end of the screen. This portion 21 of the deflecting plate is spaced apart from the rear wall a sufficient distance to permit the upper end of the screen to slip upwardly behind the said portion during the placing of the screen.

It will be noticed that the screen frame is of a width corresponding approximately to the width of the casing 1 and that it may be inserted into the casing and removed there from through the opening 9. Then in place however, the side membersll of the screen fit against the side walls of the casing. The

screen is inserted by passing the upper end through the opening 9 and upwardly beneath the lower end of the portion 21 of the deflecting plate, and the screen is pushed up until the lower end thereof, that is, the connection betweenthe bodies of the side members 11 and the doubled-over portions I 14 will pass over'the lower end members of the frame 10. The screen is then permitted to slip downward until the portions 15 will rest upon'the lower end of the opening 9, and with the pins 18 engaging outside of the said frame 10.

To brace the screenwhen in place a rod 22 is arranged transversely of the casing,

the said rod being passed through the side walls as shown in Fig. l, and having its ends headed as indicated at 23, or in any other desired manner. The rod 22 is at about the center of the screen.

A plate 24: is arranged in the casing above the screen, the upper end of the plate having a bearing 25, which encircles a rod 26 arranged transversely of the casing, near 7 the upper end and slightly in front of the center of the casing. The plate hangs vertically, and the lower end thereof is curved slightly toward the screen as indicated at 27. This lower end is slightly'below the center of the screen, and the free lower end of the plate is spaced apart forwardly from the screen. The plate hangs below the upper end of the opening 9 a little distance,

as will be evident from an inspection of v Fig. 3, and the said plate is a splash plate and guard to prevent splashing of the water through the opening 9. It will be noted that this plate hangs directly in front of the point where the water coming through the nipple 5 will strike the screen, and it will prevent splashing of the water from any cause. -By spacing the free edge or;

the splash plate away from the screen slightly, there will be no hindrance to the 7 free passage of the impurities down on theouter face of the screen. In practice, the improved filter is place in the down spout of the building in vertical position, and it will be evident that the water dischargedthrough the nipple 5 will strike the screen, and the water will pass through directly, leaving the impurities on the upper face of the screen. Some of the water will pass down under the screen, following the screen, and the solid portion 17 at the junction of the body of the screen with the apron or deflecting portion will deflect this water downward into the casing,

and will also deflect the impurities over the apron and outside of the casing.

The elbow 6 being plvotally connected with the casing, may be turned in-any direction so that the improved filter may be placed without regard to the direction'from which the inclined portion of the pipe comes, since it is obvious that the elbow may be swung to either side. The elbow prevents the flow of water from striking directly on the screen. The elbow changes the direction ofthe water, and slows the flow, thus preventing injury to the screen. Were the inlet straight and attached to a down spout of considerable length,ieven a small solid body in the water would strike the screen with considerable force and might cause considerable-damage. \Vith the elbow however, this cannot occur, I

The hopper bottom strengthens the filter at this point, and insures the thorough drainage of the water from the filter; It

will be evident that since the screens are re movable, interchangeable screens may be used of different degrees of fineness.- The filter is'entirely sanitary, every part being accessible, and it is self-cleaning, the flowing'water throwing the impurities out of the casing.
